Burn trauma is an important public health concern, with increased risk for burns in children. A cross-sectional study was performed to describe the epidemiological characteristics and risk factors for burns in hospitalized Bedouin children in Soroka University Medical Center during the years 2001–2002. In a population of 558 hospitalized burn-injured patients, 282 Bedouin children were identified. Two hundred and sixty five patients (94.0%) had burns involving less than 20% of the body surface area. Cause of the burns was scald in 190 patients (67.4%), fire in 80 patients (28.4%), chemical in 8 patients (2.8%), and explosion in 2 patients (0.7%). Two female patients (0.7%) aged 11 and 17 years died of their burns that were caused by fire. The mean length of hospitalization was 9.8 days. Pediatric burn injury has become a significant public health problem in the Bedouin population of the Negev. To reduce the burden of burn injury, it is necessary to increase current efforts in prevention of burns.

Ketamine was reported to decrease cytokine production and improve survival after Escherichia coli-induced sepsis. We examined whether ketamine decreased interleukin (IL)-6 production and improved survival after 1) burn injury or 2) burn injury combined with sepsis (E. coli) at 24 h. Ketamine (10 mg/kg) or saline was given at 1 h after burn injury (G 1, 2, 5, 6), 24 h after burn injury (G 3, 4), or at E. coli inoculation (G 7, 8). Mortality was recorded for 7 days and IL-6 was measured in serum at 6 h after burn (G 1-2), 30 h after burn (G 3-4), or 6 h after sepsis (30 h after burn) (G 5-8). Burn injury only: Ketamine given immediately (1 h) after burn injury but not 24 h after, decreased the burn-induced increase of IL-6 but did not improve survival. Burn injury + sepsis: Ketamine given immediately after burn injury did not significantly decrease the sepsis-induced increase of IL-6 or improve survival. In contrast, ketamine given immediately after sepsis significantly improved survival (46.1% versus 13.3%, P = 0.008) and decreased IL-6 production (72,640 +/- 40,990 vs 332,300 +/- 32,300 pg/mL, P = 0.008). We conclude that ketamine therapy improves survival in burn injury followed by sepsis. This beneficial effect is probably achieved through interference with the inflammatory cascade, as evidenced by attenuation of the proinflammatory marker IL-6.
